Fuzzy Search with Fuse.js — Beginner Friendly Guide

If you’ve ever searched on Amazon or Flipkart and noticed how they still find what you meant even when you type “earbads” instead of “earbuds”, that’s fuzzy search in action.

Fuzzy Search Makes Life Easier

In this post, we’ll explore Fuse.js, a lightweight JavaScript library that makes fuzzy search simple. We’ll see how it works, when to use it, and why big companies don’t rely on it for large-scale search.

What is Fuse.js?

Fuse.js is a JavaScript library for fuzzy searching. Think of it as a way to make search more human — it finds close matches, not just exact ones.

In Python, we use libraries like pandas (import pandas as pd). Similarly, in Node.js we can use Fuse.js by:

const Fuse = require("fuse.js");

You can install it with:

npm install fuse.js

Why Use Fuse.js?

Fuse.js makes fuzzy search easy.
